Subjects who are undergoing total knee arthroplasty for one
or both knees due to primary knee degenerative arthritis between 55 and 85 years
of age. Year) -Kellgre-Lawrence grade (0-4, 5 stage) grade 0: no radiographic
features of osteoarthritis grade 1: Radiological findings suggest that the joint
gap is slightly narrowed and bone projections are suspected Grade 2: The
radiological findings show a narrow joint gap and clearly visible bone
protrusions. Grade 3: Radiological findings show that the joint gap is narrow,
several bone protrusions are visible, bone deformity is visible, and bone
sclerosis is visible. Grade 4: Radiological findings show that the joint gap is
clearly narrowed, large bone protrusions are observed, severe bone sclerosis and
clear bone deformity are observed. -Subjects who have fully explained the
preoperative study and expressed their intention to
participate
-Subjects diagnosed with inflammatory arthritis (rheumatic
arthritis, psoriatic arthritis, spondylosis, etc.) -Subjects with post-traumatic
arthritis in the knee due to surgery -Subjects with arthritis due to bone
necrosis in the knee due to surgery -A person with a history of infectious
arthritis in the knee joint due to surgery -Subjects with reduced range of
motion of the knee joint (more than 20 degrees of flexion construction and less
than 90 degrees of subsequent flexion) -Subjects with very severe valgus and
varus deformity (Hip-Knee-Ankle angle ± 15 degrees or more) -When the
destruction and deformation of the joint is severe, it is expected to perform
artificial joints using bone grafts, blocks, and long poles. -Subjects who are
deemed to have an impact on the analysis of results due to severe deformation of
the femur, tibia and patella including around the knee joint -If it is judged
that it is not appropriate to be included in the study by other responsible
researchers
